WATER NIETERAD RECORDER.

-SPECIFIGAT10N forming part of Letters Patent N o. 699,188, dated May 6, 1902. Application tiled November 4, 1901.v Serial No. 81,127. (No model.)

To tZZ whom t may concern:

-Be it known that LWALTER GEORGE KENT, engineer, a subject of the King of England,

residing at 199 High Holborn, in the county of 1, The chamber h is formed of a cylinder b', se-

5 Middlesex, England, have invented a certain new and useful Water Meter and Recorder, of which the following is a specification.

The object of this invention is toprovide a Water meter and recorder which shall both r'o register the total iiow of water through a main and also give a diagram record showing the variations of the rate of iioW and which shall be suitable-for use with hydraulic-power mains, where the pressure is very great. Bothi 5 the registering andthe diagram are obtained from the difference in pressure at two points in what is known as a Venturi meter 1ocated in the main and which is in reality merelyr a contraction in the main, with two 2o plpes opening therefrom, one at the narrowest part of the contraction or throat, l the other from a point in the uncontracted main a short distance upstream from the throat, such a meter being described in the specification of Pat- By my invention I makethe apparatus very compact, so that a meter and' recorder suit-v able for use with very high pressures or for ordinary Waterworks-pressures can be made 3o small enough to be placed in a hole underthe street-pavement, if necessary.

without its cover. Figs. 3 and L are vertical sections on the lines 3 3 and 4. 4. of Fig. 2. Fig. 5 is a plan of the upper part of the apparatus 4o without its cover, showing the integrating and tion with the main. is closed by a cap b5, through which the pipe matically in Fig. 3.) The pipe ct opens directly into thetop of the mercury-chamber h above the float c, resting on the surface of mercury.

cured in the casting h2, which is bored out, as shown, so as to leave anannular space around the lower part of the cylinder h', into which the mercury can pass by the holes b3. From this space a passage leads to the bottom of the tube h4, which rises up to the T-piece a2, one arm of which is in communication with the pipe a by the cock as, while the other may be put in communication with a branch a4 from the pipe Ct by the cock a5 whenever it is desired to equalize the pressure on the two surfaces of the mercury. A cock 0.6 is provided in the pipe ot, which, with the cock a3, can be closed when it is desired to cut off all connec- The mercury-chamber h a passes and which is bolted to the casting h2,

la gutta-percha washer h6 being inserted in a recess left for that purpose, so as to make a water-tightjoint. Mercuryisintroducedinto the chamber and the zero-level adjusted by the inlet 197, closed by the screw-plug hs.

Secured to the upper surface of the ioat c is a frame c', to which is pivoted a lever c2, whose ends are pivoted to pairs of arms c3 c4, the rst pair of which rock on a pivot c5,

` while the arms c4 are fast with a spindle c, In the drawings annexed, Figure 1 shows,

to a small scale, a front elevation of the whole apparatus,with the pipes conveying` the throat 3 5 and upstream pressure fromthe Venturi me ter. y Fig. 2 is a plan of the mercury-chambery turning in bearings c7, carried by the wall of vthe chamber and passing out through a passage and stufiing-box b9, its outer end being supported by a pivot cs. Fastvwith the spindle c6 is an arm o9, linked by the link'c10 to the arm d on the shaft d', rockingon pivots d2,

carried by standards cl3 on the plate d4, bolted to the cap b5of the mercury-chamber. It will be seen that as the Iioat c rises and falls owing to the difference of the upstream and throat pressures so the shaft d will be rocked. From such rocking of the shaft d the recording and registering are effected as follows:'The arm d is linked by the link d5 to an armd, rocking on the fixed pivots d7. At the center of the link d5 is a pen d8, whose point is in contact with a sheet of ruled paper `carried by the drum or cylinder e, supported on rollers e and around the lower edge of which is a ring of teeth e2, gearing with pinions e3 on spindles e4, driven by bevel-gear e5 from the ICO clock e, the whole so arranged that the cylinder e may revolve once a week. The pen d8 will thus trace out on the paper a curve the ordinates of which will vary with the rate of flow of water in the main.

In order to register the total quantity of water passing through the main, it is necessary to use an integrating apparatus. This I arrange as follows: Fast with the rock-shaft d is an arm j', linked by the link f to an arm f2 onv a shaft f3, carried on fixed pivots]EAL and provided with two lugs f5, carrying pivots f6, on which can turn an arm f7, forked at each end and carrying by pivotsfS an integratingwheel g. g is a frame turning on pivots g2 on a standard g3 and carrying a piece of glass g", pressed by the spring g5 against a knob or studf" on the armf. By this means the wheel g is pressed against the surface of the disk 7L, carried by the spindle 7L, which is rotated, say, every ten minutes by the clock e6. The disk 7L has a portion h2 of its surface raised, so that when the wheel g is on this portion h2 the frame g is turned away from the disk against the spring g5. Pivoted to the frame g is one arm t' of a bell-crank turning on the center fi', its other arm i2 carrying a forked rod i3, supporting a spindle t, carrying at one endapinion t'meshing with the toothed wheel il on the spindle 7L, constantly turned on the pivot t' by the clock e". The other end of the spindle t is journaled in a stirrup-piece t8, turning on fixed pivots i, and has upon it a wormj, gearing with a worm-wheel'y" on the shaft j?, turning in fixed bearingsj3 and actuating by the toothed wheelsjlj5 the spindlej of the counting-trainf. lt willbe seen that so long as the wheel g is on the portion 7L of the disk the spindle i4 will be held up by the bellcrank t' 'i2 and Will be turned, owing to the pinion being in gear with the wheel 6, and so the counting-train will be driven; but when the wheel g is on the portion h2 the countingtrain will not be driven. New since the pressure of water in the main varies as the square of the velocity of fiow or of the total quantity of water it will be necessary that the boundary cui've of the raised portion h2 be such that the length of path of the wheel g on the portion h may vary as the square root of the measure of the angle through which the shaftf3 is rocked.
